Abstract: A suture needle apparatus includes a needle body and a radio-frequency identification (“RFID”) chip disposed proximate to the needle body. The RFID chip is encoded with an identifying information associated with the suture needle apparatus. The RFID chip includes an electromagnetic coupling element. A suture thread is operatively coupled to the needle body. At least one of the needle body and the suture thread is an antenna selectively electromagnetically coupled to the RFID chip and, when coupled, is configured to wirelessly communicate the identifying information responsive to radio-frequency interrogation of the suture needle apparatus. A method of providing a suture needle apparatus is also disclosed.

Abstract: A time remaining display assembly for indicating the time remaining in a pressurized gas tank, adapted to be connected to a regulator having a flow rate adjuster for selecting one of a plurality of flow rate settings comprising an assembly coupled to the flow rate adjuster, the assembly having one or more time scales imprinted thereon, each time scale corresponding to one of the flow rate settings, each time scale indicating the time remaining in the tank as a function of gas pressure in the tank.
